The Health Effects Institute has launched the State of Global Air 2018. More about the analysis and report from HEI:

Background

Most of the world’s population lives in areas where air quality is unhealthy. An estimated 95% of people live in areas where ambient (outdoor) fine particulate matter concentrations (small dust or soot particles in the air) exceed the World Health Organization’s Air Quality Guideline of 10 µg/m3. Almost 60% live in areas where fine particulate matter exceeds even the least stringent WHO interim air quality target of 35 µg/m3.
